HIGH-POWERED MULTICYLINDER TN'I'ERNAL-COIVIIBUSTION ENGINE.

Application filed. December 29, 1919. Serial No. 347,994.

To all whom it may concern:

Be it known that 1, JOHN H. Hnnsnn, a citizen of the United States, residing at Morse Bluff, in the county of Saunders and State of Nebraska, have invented new and useful Improvements in High-Powered lilulticylinder Internal-Combustion Engines, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to vertical cylinders in staggered arrangement, connected with crank shaft and crank pins of peculiar and advantageous arrangement, said connection being by means of an off-set connecting rod built to accommodate the cylinders andoif-set according to the bore and stroke of crank pin and the positions of the cylinders, the crank shaft apparatus having a plurality of crank pins associated-with the p crank shaft.

The principal object of the invention is to provide a high powered internal combustion engine possessing all of the advantages of the well known V type of engine and eliminating all of its disadvantages. Under this invention the engine will have four. vertical cylinders built in quad formation, in staggered arrangement and is to be used in such quad formation and multiples thereof, and when used in multiple is joined to an extended shaft as shown in drawing at Figs. 1 and 2. Between each quad formation is a shaft bearing. Retaining all of the advantages and power of the V type of engine, this invention in addition provides a high powered engine excelling the V type in-simplicity of construction, compactness, simple connections between the engine pistons and crank shafts, less weight and eliminatin the oiling and carbon difliculties unavoi ably associated with the V type of engine. Further, this invention provides a high powered engine of eight cylinders taking up less room than the standard 6-cylinder engines, thus giving a greater amount of power in less space. However, the invention is not limited to an eight cylinder motor but is applicable to any, number of cylinders in the multiple of four and can be used in a twelve cylinder arrangement as advantageously and effectively as in an eight cylinder. Further, the advantages of this invention are such that the engine is not limited to automobiles but can be used as motor power for anything requiring an internal combustion engine of four or more cylinders.

In the drawings: Fig. 1 shows a top view of an eight'vertical cylinder high powered internal combustion engine in quad formation in staggered arrangement, between the two quad formations appearing a shaft bearing, and looking down through the cylinders at the crank shaft and crank pins in their relative positions to the cylinders. Fig. 2 is a side elevation of my crank shaft and crank pins in their relative position to the cylinders. Through Figs. 1 and 2 run vertical lines, said lines running through the center of each cylinder and crank pin showing the relation of crank shaft and crank pins to cylinders. Fig. 3 is a vertical, cross-sectional view of cylinder No. 1 and art of outside of staggered cylinder No. 2, and letter I shows the design of the connecting rod as used with all cylinders,and special attention is called to letter J show-. ing off-set in connecting rod. Letter K is'the outside of staggered cylinder No.9. Fig. 3 shows the relative position of crank pins numbered A to H. The lettering A to H in Fig. 3 shows that each pin is set at 45 degrees from center to center, making a perfectly balanced crank shaft and with power equally divided. Each of the letters A to H in Fig. 3 is the same pin shown by same letters in Fig. 2, so that it is seen that letter B in Fig. 3 and Fig. 2 is connected with cylinder No. l, and letter C in Figs. 3 and 2 is connected with cylinder No. 6, and so on, as shown in all of said figures. In a 12-cylinder arrangement the crank pins would be set at 30 degrees from center to center.

It is to be noted that the crank shaft as connected by the connecting rod shown in Fig. 3 gets a working combination resulting in a minimization of vibration.

' The cylinders, as shown in Figs. 1 and 2, are staggered and built in groups of four in one casting with a continuous water jacket encircling all four cylinders establishing a clear an complete circulation. In place of each cylinder being joined separately, four cylinders are moulded into one unit and each unit, working in conjunction with the crank shaft and crank pins as shown in the drawings constitutes a complete high powered motor. It will be readily underno Milt stood from this description that a multiplicity of these cylinder units may be connected to one crank shaft by merely extend ing the crank shaft and crank pins. This arrangement of cylinders and construction thereof in units of four in staggered arrangement has advanta es not obtainably by other arrangement. uch a construction has lessened the number of parts, and consequently an engine of high power may be built With less Weight. Also, such construction shortens the engine so that an 8-cylinder engine can be constructed Within the space of the standard 6-cylinder. Also, by this arrangement we get a better and cheaper construction than in engin'eshaving separate cylinder castings, and thus I obtain a saving in material.

What I claim is:

1. In an internal combustion engine, the combination of a cylinder block, comprising a plurality of vertical cylinders, the number of which is a multiple of four, said cylinders being arranged in staggered relation in said cylinder-block, a crank shaft provided with a separate crank for each cylinder the cranks being arranged in pairs and the cranks of each pair being angularly displaced 45 and serving adjacent cylinders.

2. In an internal combustion engine, the combination of two cylinder units, each consisting of a cylinder block having four vertical cylinder bores arranged in staggered relation. a crank shaft provided with a set of angularly disposed cranks for the cylinders of each block, the cranks of each set being arranged in pairs, the cranks of each pair being displaced 45, and serving adjacent cylinders.

Signed by me at Morse Blufi', Saunders County, Nebraska, this 26th day of December, 1919. J OiiN H. HEUSER.
